BaseButton
==========

**Inherits:** :ref:`Control<class_Control>` **<** :ref:`CanvasItem<class_CanvasItem>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

**Inherited By:** :ref:`Button<class_Button>`, :ref:`LinkButton<class_LinkButton>`, :ref:`TextureButton<class_TextureButton>`

Base class for different kinds of buttons.

Description
-----------

BaseButton is the abstract base class for buttons, so it shouldn't be used directly (it doesn't display anything). Other types of buttons inherit from it.

Signals
-------

.. _class_BaseButton_signal_button_down:

- **button_down** **(** **)**

Emitted when the button starts being held down.

----

.. _class_BaseButton_signal_button_up:

- **button_up** **(** **)**

Emitted when the button stops being held down.

----

.. _class_BaseButton_signal_pressed:

- **pressed** **(** **)**

Emitted when the button is toggled or pressed. This is on :ref:`button_down<class_BaseButton_signal_button_down>` if :ref:`action_mode<class_BaseButton_property_action_mode>` is :ref:`ACTION_MODE_BUTTON_PRESS<class_BaseButton_constant_ACTION_MODE_BUTTON_PRESS>` and on :ref:`button_up<class_BaseButton_signal_button_up>` otherwise.

If you need to know the button's pressed state (and :ref:`toggle_mode<class_BaseButton_property_toggle_mode>` is active), use :ref:`toggled<class_BaseButton_signal_toggled>` instead.

----

.. _class_BaseButton_signal_toggled:

- **toggled** **(** :ref:`bool<class_bool>` button_pressed **)**

Emitted when the button was just toggled between pressed and normal states (only if :ref:`toggle_mode<class_BaseButton_property_toggle_mode>` is active). The new state is contained in the ``button_pressed`` argument.

Enumerations
------------

.. _enum_BaseButton_DrawMode:

Property Descriptions
---------------------

.. _class_BaseButton_property_action_mode:

- :ref:`ActionMode<enum_BaseButton_ActionMode>` **action_mode**

+----------+------------------------+
| *Setter* | set_action_mode(value) |
+----------+------------------------+
| *Getter* | get_action_mode()      |
+----------+------------------------+

Determines when the button is considered clicked, one of the :ref:`ActionMode<enum_BaseButton_ActionMode>` constants.

----

.. _class_BaseButton_property_button_group:

- :ref:`ButtonGroup<class_ButtonGroup>` **button_group**

+----------+-------------------------+
| *Setter* | set_button_group(value) |
+----------+-------------------------+
| *Getter* | get_button_group()      |
+----------+-------------------------+

The :ref:`ButtonGroup<class_ButtonGroup>` associated with the button. Not to be confused with node groups.

----

.. _class_BaseButton_property_button_mask:

- :ref:`MouseButton<enum_@GlobalScope_MouseButton>` **button_mask**

+----------+------------------------+
| *Setter* | set_button_mask(value) |
+----------+------------------------+
| *Getter* | get_button_mask()      |
+----------+------------------------+

Binary mask to choose which mouse buttons this button will respond to.

To allow both left-click and right-click, use ``MOUSE_BUTTON_MASK_LEFT | MOUSE_BUTTON_MASK_RIGHT``.

----

.. _class_BaseButton_property_button_pressed:

- :ref:`bool<class_bool>` **button_pressed**

+----------+--------------------+
| *Setter* | set_pressed(value) |
+----------+--------------------+
| *Getter* | is_pressed()       |
+----------+--------------------+

If ``true``, the button's state is pressed. Means the button is pressed down or toggled (if :ref:`toggle_mode<class_BaseButton_property_toggle_mode>` is active). Only works if :ref:`toggle_mode<class_BaseButton_property_toggle_mode>` is ``true``.

\ **Note:** Setting :ref:`button_pressed<class_BaseButton_property_button_pressed>` will result in :ref:`toggled<class_BaseButton_signal_toggled>` to be emitted. If you want to change the pressed state without emitting that signal, use :ref:`set_pressed_no_signal<class_BaseButton_method_set_pressed_no_signal>`.

----

.. _class_BaseButton_property_disabled:

- :ref:`bool<class_bool>` **disabled**

+----------+---------------------+
| *Setter* | set_disabled(value) |
+----------+---------------------+
| *Getter* | is_disabled()       |
+----------+---------------------+

If ``true``, the button is in disabled state and can't be clicked or toggled.

----

.. _class_BaseButton_property_keep_pressed_outside:

- :ref:`bool<class_bool>` **keep_pressed_outside**

+----------+---------------------------------+
| *Setter* | set_keep_pressed_outside(value) |
+----------+---------------------------------+
| *Getter* | is_keep_pressed_outside()       |
+----------+---------------------------------+

If ``true``, the button stays pressed when moving the cursor outside the button while pressing it.

\ **Note:** This property only affects the button's visual appearance. Signals will be emitted at the same moment regardless of this property's value.

----

.. _class_BaseButton_property_shortcut:

- :ref:`Shortcut<class_Shortcut>` **shortcut**

+----------+---------------------+
| *Setter* | set_shortcut(value) |
+----------+---------------------+
| *Getter* | get_shortcut()      |
+----------+---------------------+

:ref:`Shortcut<class_Shortcut>` associated to the button.

----

.. _class_BaseButton_property_shortcut_context:

- :ref:`Node<class_Node>` **shortcut_context**

+----------+-----------------------------+
| *Setter* | set_shortcut_context(value) |
+----------+-----------------------------+
| *Getter* | get_shortcut_context()      |
+----------+-----------------------------+

The :ref:`Node<class_Node>` which must be a parent of the focused GUI :ref:`Control<class_Control>` for the shortcut to be activated. If ``null``, the shortcut can be activated when any control is focused (a global shortcut). This allows shortcuts to be accepted only when the user has a certain area of the GUI focused.

----

.. _class_BaseButton_property_shortcut_in_tooltip:

- :ref:`bool<class_bool>` **shortcut_in_tooltip**

+----------+----------------------------------+
| *Setter* | set_shortcut_in_tooltip(value)   |
+----------+----------------------------------+
| *Getter* | is_shortcut_in_tooltip_enabled() |
+----------+----------------------------------+

If ``true``, the button will add information about its shortcut in the tooltip.

----

.. _class_BaseButton_property_toggle_mode:

- :ref:`bool<class_bool>` **toggle_mode**

+----------+------------------------+
| *Setter* | set_toggle_mode(value) |
+----------+------------------------+
| *Getter* | is_toggle_mode()       |
+----------+------------------------+

If ``true``, the button is in toggle mode. Makes the button flip state between pressed and unpressed each time its area is clicked.

Method Descriptions
-------------------

.. _class_BaseButton_method__pressed:

- void **_pressed** **(** **)** |virtual|

Called when the button is pressed. If you need to know the button's pressed state (and :ref:`toggle_mode<class_BaseButton_property_toggle_mode>` is active), use :ref:`_toggled<class_BaseButton_method__toggled>` instead.

----

.. _class_BaseButton_method__toggled:

- void **_toggled** **(** :ref:`bool<class_bool>` button_pressed **)** |virtual|

Called when the button is toggled (only if :ref:`toggle_mode<class_BaseButton_property_toggle_mode>` is active).

----

.. _class_BaseButton_method_get_draw_mode:

- :ref:`DrawMode<enum_BaseButton_DrawMode>` **get_draw_mode** **(** **)** |const|

Returns the visual state used to draw the button. This is useful mainly when implementing your own draw code by either overriding _draw() or connecting to "draw" signal. The visual state of the button is defined by the :ref:`DrawMode<enum_BaseButton_DrawMode>` enum.

----

.. _class_BaseButton_method_is_hovered:

- :ref:`bool<class_bool>` **is_hovered** **(** **)** |const|

Returns ``true`` if the mouse has entered the button and has not left it yet.

----

.. _class_BaseButton_method_set_pressed_no_signal:

- void **set_pressed_no_signal** **(** :ref:`bool<class_bool>` pressed **)**

Changes the :ref:`button_pressed<class_BaseButton_property_button_pressed>` state of the button, without emitting :ref:`toggled<class_BaseButton_signal_toggled>`. Use when you just want to change the state of the button without sending the pressed event (e.g. when initializing scene). Only works if :ref:`toggle_mode<class_BaseButton_property_toggle_mode>` is ``true``.

\ **Note:** This method doesn't unpress other buttons in :ref:`button_group<class_BaseButton_property_button_group>`.
